ID:176080 Can't place Flexible LVDS or differential I/O <name> in row <number> <name> side -- minimum spacing must be <number> row(s) away from the I/O in row <number>

CAUSE: The Fitter tried to place the specified Flexible LVDS or differential I/O in the specified row and side. However, the Flexible LVDS or differential I/O placement does not meet the specified minimum spacing requirement away from the existing I/O in the specified row. The minimum spacing requirement is necessary to limit noise along the power line. As a result, the Fitter cannot place the Flexible LVDS or differential I/O.

ACTION: Modify the design so that the spacing between the Flexible LVDS or differential I/O and the existing I/O meets the specified minimum spacing requirement.
